Typically modules will call it: $controller->set_grade_range(make_grades_menu($gradingtype), $gradingtype > 0); Negative $gradingtype means that scale is used and the grade must be rounded to the nearest int. Positive $gradingtype means that range 0..$gradingtype is used for the grades and in this case grade does not have to be rounded.
